WHEEL.

Specification of Letters Patent.

Application filed October 24, 1912. Serial No. 727,581.

To all whom it may con cern Be it known that I, CLARENCE L. TOMLlN SON,a citizen of the United States, residing in the city of Portland, countyof Multnomah, and State of Oregon, have invented certain new and usefulImprovements in Wheels, of which the following is a specification.

My invention relates to wheels, and more particularly to certainfeatures of improvement in the construction of the hub portion thereofwhereby the spokes of wheel can be adjusted radially for the purpose ofex panding the felly within the tire, thereby tightening the latter andmaking the wheel more rigid and serviceable.

One of the salient objects of my invention is to provide certainimprovements in the construction of the Wheel shown and de scribed in myU. S. Letters Patent No.

926,626, issued to me under date of June 29,

1909, and also in the construction of the wheel shown and described inmy pending application filed April 3, 1912, under Serial No. 688,297,whereby to overcome certain objections thereto.

In this improvement i do away with a threaded cone and thereby avoid anytwisting or shifting of the inner ends of the spokes as the cone isscrewed into place. I

also use fewer gibs at the inner ends of the spokes and at the same timeget a better and stronger construction, for the reason that the inner,or butt, ends of the spokes can be made larger, and instead of putting ahole through the inner end of each spoke for the holding bolt, I use onehole between the butt ends of alternate pairs of spokes, therebyremoving only half as much material from the ends of the spokes inmaking theholes.

By using fewer gibs and placing them be tween alternate pairs of spokeends, instead of between every two ends, I am able to use a gib ofgreater angle, and thereby secure a relatively greater pressure radiallyoutwardly at the butt ends of the spokes, as saidgibs are forcedoutwardly.

Other improvements and advantages will be apparent from the followingdescription of the invention, shown in the accompany ing sheet ofdrawings, and in which,-

portion 1, of angular for-min cross section,

constitutes a part and cooperates with the flange 2 in receiving andholding therebetween the spokes 5. Slidablymounted upon the axle box 3,is a cone element 6, provided exteriorly with longitudinally extendingribs 7. Mounted between the inner or butt ends of alternate pairs of thespokes 5, are wedge shaped gibs 8, provided. in their ends with grooves,as9, adapting them to fit upon the ribs 7 ofthe cone element 6. Betweenalternate pairs of spokes, at their butt ends, I provide elongated holes10 to receive bolts 11, through the flange 2 and the ring 1, asindicated, whereby to clamp the inner ends of the spokes therebetween.It will be noted that I alternate the gibs 8 and the bolts 11, insteadof putting gibs between every pair of spokes, and a hole through eachspoke end. As a means for forcing the cone element 6 inwardly, I providea nut 12, adapted to screw upon the axle box 3, with a lock nut 18, forsecuring it in place. An outer shell portion 141 of the hub body is alsoscrewed on to the axle box 3 and into interfitting engagement with thering 1, thereby inclosing the whole and giving a neat appearance to thehub.

By this construction and arrangement, it will be readily seen that Iavoid the threaded cone referred to, which must be screwed into place,and to which there is more or less objection, and instead thereof,1pro-- vide a construction whereby an expanding (one element is slidablymounted upon an axle box and has a sliding engagement; with a series ofgibs, especially adapted thereto, and which, when forced outwardly bysaid cone element, produce a more direct longitudinal movement of saidspokes outwardly.

I am aware that slight changes and modifications can be made in theembodiment of the invention here shown and described for purposes ofillustration, and I do not, therefore limit the invention to theparticular showing here made, except as I may be limit ed by tie heretoappended claims.

of the hub shellor body I claim:

1. In a Wheel, the combination with a hub body, spokes, a felly, tire,and an axle box in said hub threaded exteriorly, of a cone shapedelement mounted to slide longitudir nally on the axle box, a series ofWedges interposed between the butt ends of the spokes and slidablyengaging the coneshaped element, said cone shaped element being spacedfrom engagement with the spokes, and the spokes resting at their innerends entirely upon the said wedges, and a nut upon the axle box forforcibly sliding said cone shaped element longitudinally between theaxle box and the said wedges for the purpose set forth.

2. In a Wheel, the combination with a hub body, spokes, a felly, tire,and an axle box in said hub threaded exteriorly, of a coneshaped elementmounted to slide longitudicoplei of this patent inay be obtained forfive cents each, by addressing the nally on said axle box and providedwith ribs extending longitudinally thereof, said cone-shaped elementbeing spaced from the inner ends of the spokes, a series of gibsinterposed between the butt ends of some of the spokes and slidablyengaging the coneshaped element, said gibs having grooves at their innerends extending longitudinally thereof adapted to slidably fit the ribsupon the cone-shaped element, a nutthreaded on the axle box for forciblymoving the coneshaped element upon the axle box in engagement with saidgibs, for the purpose set forth.
